Изобретение относитс к машиностроению , а именно к Механизмам, генерирующим на выходном валу гармонические и различной формы полигармонические импульсы вращательного момента, в том числе и знакопосто нные .The invention relates to mechanical engineering, namely to Mechanisms that generate harmonic and polyharmonic rotational moment pulses, including sign-constant, on the output shaft of the shaft.

Известен импульсный механизм, содержащий ведущий и ведомый валы, водило, сателлиты с инерционными грузами, выполненными в виде подпружиненных катков, снабженных механизмами радиального перемещени грузов в виде скрепленных с сателлитами направл ющих, их ползунов, а также обойм, взаимодействующих с катками и закрепленных на водиле со смещением относительно сателлитов 1.A pulsed mechanism is known that contains the drive and driven shafts, the carrier, satellites with inertial loads made in the form of spring-loaded rollers, equipped with mechanisms for the radial movement of loads in the form of guides attached to the satellites, as well as clips interacting with the rollers and fixed on the carrier offset relative to satellites 1.

Однако во врем работы механизма периодически измен етс контактное давление подпружиненных катков о внутренние беговые дорожки обойм, что приводит к неравномерному износу близлежащих к центру вращени сателлитов зон обегани обойм.However, during the operation of the mechanism, the contact pressure of the spring-loaded rollers on the inner racetracks of the clips periodically changes, which leads to uneven wear of the zones around the clips around the center of rotation of the satellites.

Наиболее близким по технический сущности к изобретению вл етс импульсный механизм, содержащий ведущий и ведомый валы, центральное колесо и водило, установленные соответственно на ведущем и веДомом валах, размещенные на ос х в водиле сателлиты с диаметральными направл ющими И установленными с возможностью перемещени вдоль них неуравновешенными грузами , кинематически св занные с последнй ми обоймы по числу сателлитов, установленные с возможностью поворота в водиле на ос х, расположенных эксцентрично ос м сателлитов .The closest in technical essence to the invention is a pulsed mechanism containing a driving and driven shaft, a central wheel and a carrier mounted respectively on the driving and driving shaft, placed on the axes in the carrier satellites with diametrically guided AND installed with the ability to move along them unbalanced loads, kinematically associated with the last clips by the number of satellites, mounted with the possibility of turning in a carrier on axes, located eccentrically with the satellites axes.

Кроме того, в водиле установлены обоймы по числу сателлитов с внутренней рабочей поверхностью. Неуравновешенные грузы выполнены В виде катков, непосредственно взаимодействующих с обеими обоймами 2.In addition, the holder installed clips on the number of satellites with an inner working surface. Unbalanced loads are made in the form of rollers, directly interacting with both clips 2.

Износ рабочих поверхностей при этом 15 уменьшаетс , однако обе известные передачи не позвол ют мен ть режим ее работы и в виду отсутстви в них механизма настройки на генерирование различных форм полигармонического вращающего момента.The wear of working surfaces in this case decreases, however, both known gears do not allow changing its mode of operation and since they lack a tuning mechanism for generating various forms of polyharmonic torque.

Цель изобретени - регулирование форм импульсов вращающего момента.The purpose of the invention is to regulate the shape of torque pulses.

Claims

The goal is achieved by the fact that in a pulsed mechanism containing a driving and driven shaft, a central wheel and a carrier mounted, respectively, on the driving and driven shaft, satellites placed on the axes in the carrier, with satellites guiding and installed with unbalanced loads, kinematically associated with the latter clips but the number of satellites installed with the possibility of rotation in the carrier on the axes located eccentrically with the axis of the satellites, the kinematic connection is made in the ideas of shatunov, hingedly connected by one horse with unbalanced cargoes, and the other eccentrically mounted on the cage, the eccentricities are equal to half the length of the sadons, and the mechanism is equipped with a central wheel mounted on the driven shaft with the possibility of a fixed rotation relative to it and interacting with clips. FIG. 1 Guinea kinematic scheme of a pulsed mechanism; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. 1. The impulse mechanism contains the leading 1 and the driven 2 shafts, on which the central wheel 3 and the carrier 4 are mounted. In the latter, the satellites 5 are mounted on the axles, engaging with the central wheel 3 and carrying diametrically guides 6, in which of the sliders 7, unbalanced weights 8 are installed. In the carrier 4 on the axles, eccentric axles of the satellites 5, clamps 9 are rotatably mounted, kinematically associated with unbalanced weights 8. The kinematic link is made in the form of shatunov 10, each of which is ball irno coupled at one end to the unbalanced load 8, and the other - with a finger 11 mounted in a holder 9 eccentrically to its axis. The magnitudes of the eccentricities of the fingers 11 relative to the axes of the holder 9 and the latter relative to the axis of the satellites 5 are equal to half the length of the rods 10. On the driven shaft 2 with the possibility of fixed rotation, a central wheel 12 is installed, interacting with the holder 9, for example, by means of gearing. The impulse mechanism works as follows. From the drive shaft 1 and the central wheel 3, satellites 5 pivot around their axes, KOTopbie create on the carrier 4 and the driven pulses of torque. When the satellites 5 rotate, the slides 7 with weights 8 slide along the guides 6 and at the same time due to the rods 10 rotate around the fingers 11. As a result, the distance of the centers of gravities of the loads 8 relative to the centers of rotation of their satellites 5 changes, which leads to polyharmonic the nature of the pulses of torque. The combination of the fingers 11 with the centers of rotation of the satellites 5 leads to obtaining a harmonic alternating moment, and when the fingers 11 are removed from the axis of the satellites 5 by an amount of length}, the sign-constant rotating moment is obtained. The change in the position of the fingers 11 and, thus, the pulse pulse shape is achieved by means of a fixed rotation of the central wheel 12. The feasibility of the pulse mechanism is provided by the ability to adjust it to various forms of the dynamic torque, from harmonic alternating to polyharmonic sign-standing.
